Spurs 'sitting on a fortune' with Alli and Kane assets

Tottenham are sitting on a potential profit of £316million for Harry Kane and Dele Alli, according to a new study.

The CIES Football Observatory has calculated that England striker Kane, brought through the ranks at Spurs, would be worth more in profit to the north Londoners than Lionel Messi at Barcelona.

The number crunchers have worked out the 50 players in the 'big-five' leagues - England, Spain, Italy, France and Germany - with the most positive gap between their current transfer value and the fee paid for them by their clubs.

Homegrown Kane, 24, is worth an estimated £173m (198.2m euros) to Spurs while Messi, who also cost Barca nothing, would command a fee of £172m (196.8m euros), according to the Football Observatory algorithm.

Messi's value is reduced due to his age. The Argentina superstar will be 31 in June.

Alli, 21, cost Tottenham an initial £5m from MK Dons in 2015 and has a potential added value of £143m (164m euros).

France striker Antoine Griezmann would be worth a £138m (157.6m euros) profit to Atletico Madrid, although that figure does not take into account his reported 100m Euro buy-out clause.
